hello all

converting from mon dd yyyy hh:miAM to yyyy-mm-dd

i have tried CONVERT(varchar, @fup_date,120)
which retrured yyyy-mm-dd plus the hh:mi:ss(24h).is there a specific style which return only the yyyy-mm-dd or do i have to manually truncate the "hh:mi:ss(24h)" portion of it?

thanks in advance

You can use CONVERT(DateTime,FLOOR(CONVERT(Int,GetDate()))) to return a value for the given date at midnight, which is really how SQL views/stores a date without an explicit time.  If you're asking how to just display that datevalue only, then you have to use string manipulation.

Sorry, replace GetDate() with the date/time value you want to change.
              CONVERT(DateTime,FLOOR(CONVERT(Int,@MyDateTimeVariable)))

Interesting pique_tech, I've always used the technique written by MartinCMS, but I like the integer conversion.

A note though, you'd need to convert it to a float, not an int.  If it's an integer, it will have already rounded off the decimal portion itself before ever reaching you're FLOOR command, so anything after noon would come up as midnight of the next day.

Thanks, you're right:  I actually made that same mistake myself a long time ago (thus I forgot and did it again).

So, the final, correct version of my suggestion is, using spankenstien's variable name:
             CONVERT(DateTime,FLOOR(CONVERT(Float,@fup_date)))
